Space High Voltage Power Module Design

With the rapid development of world aerospace technology, next-generation technologies such as high-power electric propulsion, space welding and future space solar power stations have put forward higher requirements on the power level, reliability and conversion efficiency of space high-voltage power supplies. The key to space high-voltage power supply design is to improve the reliability and efficiency of the power supply. Aiming at this situation, this paper proposes a high-reliability space high-voltage converter. Based on the experiments, we take the phase-shifted full bridge series resonance circuit to optimize the efficiency of the high-voltage converter, the optimization results and electric field of the experimental circuit board are simulated and verified. Finally, the development direction of space high-voltage power supply is summarized and the outlook is put forward.
